Zusammenfassung:	PURPOSE:To ensure weight which is capable of resisting against an external force produced during installation and to stabilize a caisson during installation, by a method wherein weight cells are temporarily placed on the sunk caisson, and sea water is poured in the tank part of the weight cell. CONSTITUTION:A caisson 1 is installed in a position as water is poured in chambers 5 in the caisson 1, weight cells 2 are placed on the caisson 1, water is poured into a tank part 4 of the weight cell 2, and weight, which is capable of resisting against an external force produced during installation. Sand is charged in a chamber 6 in the caisson 1 through a through-hole 3 in the weight cell 2, and after filling sand is charged, water in the weight cells 2 is drained. After drainage is completed, the weight cells 2 is transported to other caisson, which is intended to be installed, with the aid of a crane ship.
